Yes, now the "loop" devices are dynamically allocated.... a patch to
provide the 8 "static allocated" loop devices is already in current git
(post -rc4, will be in -rc5).

The kernel on-demand loop device instantiation breaks several user space
tools as the tools are not ready to cope with the "on-demand feature". Fix
it by instantiate default 8 loop devices and also reinstate max_loop module
parameter.
